AIR-HEATER FOR GASOLENE-ENGINES.

Specification of Letteis ,Patent.

'Patente'd April 6, 1909.

Application filed January 26, 180B Berta! No. 412,671.

To all whom it may concern:

Be it knownthat I, Crunnes B. Crux nsus, citizen ofiithe United States, residing at Milo, in the county of Vernonand State of .dissouri, have invented certain new and useful Improvementsin Air-Heaters for GasoleneJLngines, of which the following is n specification. 1' This invention has for its ob'ect it simple and ellicient construction of device or at tachlnent for use with internal combustion engines-,1particularly thosethnt are used on the farm and in other exposed places, where, as is well known, itoften becomes difficult to start theengine especially in cold weather, owing to .lllu fact, that the air that is' fed into the niixingfhafnher is so cold that it will not generate with the gasulene,

a mixture of the proper temperature to effeet the proper combustion and eizplosion. More specifically my invention has for its objeetnnair heatingd'evice designed 'to .properlyheat the'air before it fed'tothe imiqngehamberof the gasolene on otherint'crn'ail combnstibu engine, and tho-invention consists, in certain constructions;arrange-' ments and eo'mbimitionsfo the partslthat I shall lidre-inafter 'fully lee e-antliclaim.

For 'a' full :understa v of {the ;in \"en-;v tion,- rcferencciis to, be .had' aofth'o following description and accompanying'drau'ings,in

- which ci:ted in all the views of t e d "the same reference characters.

be formed of any desired number of ham or com olutions suitably connected to ethor by any desired fittings, such as the el ows,

un'dreturn bends shown intheaccompanying drawings, and ajacket '3 which is tie-- signed. to inclose' the coil 2 so as to protect the same from cold, air and' at the same to the mixing time confine to the coil theheat that; is generated by gasolene fed to the burner 4, said burner being connected by the pi e 5 to the gasoleno pipe 7 of the engine. lhe jacket 3 may be suspended from the air pipe 1 by means of bails or cars 5 as shown.

From the foregoing description in connection with the accompanying drawing, it

. 'iseridcnt that in the practical operation of my improved air heater for gasolene en glues"; gasolene may be fed from the pipe 5 through the burner 4, and being lighted the flame will heat the jacket 3 and the coil 2 so that the fresh an passing through the coil will; be properly heated before it, is

passedtdithe mixinr chamber to produ'ce a warm mixture so that the enginemay be Quickly and easil started:

'Itwill be note 'by reference to' Fig. 1 of the drawings that the jacket 3 and the heating coil 2 are located underneath the cylinder of the engine, the inlet pip? 1 opening into the; hpllow bed of the-en inc. By this means, it is obvious that the urncr 4 maybe used for only the initial operation of heating the air for as soon as the engine jheats up, the bed itself will bccorne \yarm enough to properly heat the air as It passes into the pipell. r V Havimr' thus described the in ventiomwhat is claimed as newis; Thecom'bination with a-gasolne engine embodying a bed and a cylinder mounted thereon and projecting atone end. over or beyond the'bcd, the engine also embodlyin a mixingchamber and a g'asol cne pipe1ea ing to-said chamber. an ail" inlet pi oesttending into the bed and openingtiereln and leading therefrom into the, mixing 'fllalllbfl. said pipe being'bent intermediate its ends-into coil. :1 jacket surrounding said coils'and suspended from the air inlet pipe *ntpliintson either side of said, coils, a branch pipeconnec ed to and leading down-. wardlu from the ,gflse lenc supply pipe and provided with n hotiaihtfilly extending portion and a burner secured to said portion and'supp'orted underneath the jacket.

In testimony whereof I atlix my signature in presence of two witnesses.-
